genetic
information
•Genetic material of organism—transmitted from a
mother cell to its daughters during cell division
•Transmission of genetic material from one cell or
organism to another-based on ability of double
stranded DNA molecules to be replicated
•DNA replication: extremely exact-molecules
containing hundreds of millions of nucleotide base
pairs are duplicated with few mistakes (if any)
•P r o c e s s o f D N A r e p l i c a t i o n b a s e d o n
complementary nature of strands, making up DNA
duplex molecules: these strands held together by
H-bonds between specific base pairs
•Bonds br eak—s eparat ed s t rands s e rve as
templates for synthesis of new partner strands
